Thanks for the kudos.

It was really nice to meet ya'!

 

Great Post and Great Mod!

 

Where could I find the 270uF capacitor... none on eBay or in the first ten pages of results...

Thanks,
Anthony

 

It would be easier to just go to Radio Shack or any electronics store and get it.

 

Here is a 330uf I used. Sounds great !!!

Amazon.

 

This link is for a 27uf and 400v ...most used are 100v or less

I ordered these and they arrived today. They are much bigger than I expected...about 3/8" x 1.75". Will they fit in the door?

I was hoping to do the mod this weekend.

Thanks

 

No problem. You could fit a small cat in there.
With proper preparation, of course!

 

OK Thanks!

 

There is plenty of room for them.
Just be sure no bare wire is exposed.
These have some very long wire leads on them.

 

I noticed that. It leaves lots of wire to work with then cut off the excess when done and cover the exposed. Thanks

 

I am really looking forward to the directions to do this mod. I don't know a whole lot about this stuff but I know my audio isn't that great and I look fiorward to it.

 

It's so easy, even a caveman can do it. But seriously, it just took me five minutes per door and now I can crank up the system without any shake, rattle and roll.

 

From post #21

This is the procedure:

1. Pop off the panel with a screwdriver.
----> Use a small flathead screwdriver and with a little finesse, the panel will pop right out.

2. Reach in and disconnect the rear connector (the one with two wires, not five!).
----> Squeeze in the two tabs on each side, and pull the connector downwards. When it disconnects, there is enough play in the wire to pull it out of the door panel several inches. You will have to pull back the black cloth sleeve that protects the wires inside.

3. Install the capacitor.
----> I have two different procedures for this. Cut one wire and splice in the capacitor using either 1) wire nuts or 2) crimp connectors.
----> The capacitor can be wired in series with either the red or the black wire. It doesn't matter.
----> Capacitor values in this range are usually polarized. This means that one end has to be connected to the more positive voltage side of the circuit. In our case, this is a don't care and it doesn't matter which way the cap is oriented. This is because there is no DC voltage level at the amplifier output (actually there is always a few millivolts of DC, but never enough to worry about).
----> In summary, the capacitor is put into series with either the black wire or the red wire, and it doesn't matter which way the cap is "pointing" in this series connection.

4. Reconnect the plug and pop the panel back into the door. Done! Enjoy your great "new" stereo!

For my tastes, Before the mod, I usually had the bass control set at -7, -8 (or sometimes even -9) to prevent the front speakers from over loading and distorting from too much bass. After the mod, the bass can be put all the way up to around -5 to about +2, depending on the material.

I will state that however easy and safe this procedure is, I am not responsible for any damage incurred by anybody performing this to their Crossfire, either to their person or to their vehicle and/or other property.

Good Luck and have fun!

 

Thanks so much for this information. I will go to a Radio Shak and ask for one of those things. I will install it to the red wire. It looks pretty easy to do and then the stereo sounds a lot better. How much better? As in like a totally different system better? This is pretty cool. Thanks again. This is a pretty cool site. Any other little must do mods that I have not come across yet that would be a good idea to do like this one???? Thanks a million!

 

Be sure to buy 2 of these (one for each door)
You may not find them at Radio Shack either but the are available online with the link I provided below

Once I received my 330uf non polarized caps and it took only a half hour to install them. As most everyone posted already here it definitely cuts back the bass in the door speakers and allows the sub woofers behind the seats to pump the bass harder.
Overall I like the mod and plan to keep it as it is.
I played a variety of CD's and enjoy the noticeable difference.

Thanks I will order those from your link and then I will install them when I get them. Thanks for the help. Do you know anything about the Sprint Booster kits for the XF's. This stuff is all new to me and you seem to know a lot about the XF's? Are they worth the money? People have been talking about the change and increase to the pick up and exceleration of the car the way the stereo is enhanced by this mod. Heck if I can make my Audio system sound way better and give the car way better pick up all in one week end for a few hundred bucks that sounds great to me. What do think?
